PRO2A 10.5" 300 Blackout 1/7 or 1/5 Pistol Length Melonite AR-15 Upper with Flash Can Kit

Product Overview

The PRO2A 10.5" 300 Blackout 1/7 or 1/5 Pistol Length Melonite AR-15 Upper with Flash Can Kit delivers a highly optimized configuration designed to maximize personal defense capabilities. This setup wraps an advanced linear muzzle device inside an extended free-float handguard, protecting the operator from lateral blast signature while retaining the absolute ideal barrel length for the .300 AAC Blackout cartridge.

Key Features

Integrated Muzzle Blast Mitigation: Pre-installed slimline flash can routes explosive gases and concussion forcefully forward, shielding the shooter in confined environments.
Dynamic Twist System Profiles: Configure your build using a traditional 1:7 twist for a wide operational envelope, or select the hyper-fast 1:5 rotational rate to impeccably stabilize heavy subsonic ammo configurations.
Extended Handguard Architecture: Extended free-float rail recesses the muzzle assembly cleanly beneath the handguard for maximum grip real estate and sleek aesthetic integration.
Liquid Melonite Treatment: Full-immersion QPQ treatment creates a highly durable micro-surface on the 4150 CMV barrel to prevent friction wear and severe elemental erosion.
